Larsen, Carpinteria, Calif., assignor of one-half to Raymond A. Doell Application August 19, 1949, Serial No. 111,251 1 Claim. (Cl. 189-36) This invention relates to a novel frame structure of steel or other suitable metal for forming a building frame and having channels for receiving and anchoring therein edge portions of suitable composition wall board or panel forming the exterior and interior walls of a building.

More particularly, it is an aim of the present invention to provide novel construction studs forming the framework of a metal building structure which readily adapts itself to the prefabrication of buildings of different sizes.

Still a further object of the invention is to provide thereby.

Still a further object of the invention is to provide a metal building framework which will readily lend itself for use as conduits for heating or ventilating and for electric wiring.

Still a further object of the invention is to provide a metal building framework which readily lends itself to economical building construction without sacrificing strength or durability.

Numerous other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating a preferred embodiment thereof, and wherein:

The single figure is a cross sectional view of the interior or exterior stud member.

Referring more specifically to the drawing, an upright stud member of a metal building frame is illustrated and is designated generally c and includes a base member, designated generally 110, which is bent lengthwise to provide an intermediate portion 120, corresponding edge portions 130 which are disposed parallel to the intermediate portion 12c and parallel portions 140 connecting the edge portions 130 to the intermediate portion 120. The edge portions 13c are disposed in the same plane and said connecting portions 140 are disposed at right angles to the portions 13c and to the intermediate portion 12c. The stud 10c also includes a fiat elongated plate 15c the width of which is substantially greater than the over-all width of the base member 11c, measured from the outer edges of the portions 13c and which is secured by nut and bolt fastenings 160 to the outer side of said intermediate portion 120 and so that each side edge 17c of the plate 150 will cooperate with the complementary edge portion 13c and the portion 14 to form a channel 180. The two channels 18c of the stud 10c open outwardly in opposite directions. The heads of the bolts of fastenings 160 seat in counterbored openings 190 of the plate or strip 150 so that the heads thereof are disposed flush with the exposed side of said plate.

The stud 10c is provided with a pair of longitudinally extending clamping strips 40 having corresponding outwardly offset portions 41 which bear against the inner sides of the portions 140 of the base member 110 and which are secured thereto by nut and bolt fastenings 42 which extend through registering openings 43 in the portions 14c and 41. The heads of the fastenings 42 are disposed in the channels 180 and the nuts thereof are disposed internally of the stud 100. The strips 40 2,708,494 Patented May 17, 1955 have inwardly offset edge portions 44 which project from the plane of the portions and which combine to form parallel clamping members between which an edge of a wall member 39c is clamped for positioning the wall member 390 at a right angle to the wall members 20c and 210.

Before the plate is secured by the fastenings 16c to the intermediate portion 12c of the base member 11c, adjacent edges of two wall members 20c and 210 are positioned substantially in abutting engagement with the outer sides of the portions 14c. Said wall members 200 and 21c may be formed of a suitable composition material, used for internal and external walls of dwellings and other buildings. The strip 150 is then applied and secured by the fastenings 160, as previously described, so that adjacent edges of the wall members 200 and 21c will be clamped in the channels 18c between the edge portions 130 and the complementary side edges 17c of the strip 15c for elfectively securing the wall members 20c and 210 to the stud 100.

It will be readily apparent that the stud 10c can be most effectively assembled to engage the wall members 200, 21c and 390 by applying the wall member 390 initially, after which the fastenings 42 may be tightened for drawing the portions 44 toward one another and into clamping engagement with the wall member 390, the thickness of which is greater than the spacing between the portions 44, before the fastenings 42 are tightened. The wall members 200 and 210 are thereafter applied and secured in the channels or grooves by thereafter applying or tightening the outer plate 15c.

Various other modifications and changes are contemplated and may obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter defined by the appended claim.

I claim as my invention:

A frame stud of a building construction comprising a base member of angular cross section including substantially parallel sides and an intermediate portion extending between corresponding edges of said sides and disposed at a right angle thereto, said sides having outturned flanges disposed in the same plane and parallel to said intermediate portion, and a plate secured to the outer side of said intermediate portion and having side edges extending beyond said parallel sides and cooperating with said flanges to form oppositely opening channels adapted to receive adjacent edges of wall members disposed in the same plane, a pair of corresponding strips disposed against the inner surfaces of said sides and having extensions projecting beyond said outturned flanges and disposed at right angles thereto to form a third channel adapted to receive an edge of a third wall member disposed substantially at a right angle to the aforementioned wall members, and fastening means detachably securing said strips to said sides and for displacing the strips toward the sides to displace said extensions toward one another, the distance between the facing surfaces of References Cited in the file of this patent UNITED STATES PATENTS OTHER REFERENCES Popular Science, March 1947, page 125.
